A landscaper is designing a flower garden in the shape of a trapezoid. She wants the length of the shorter base to be 3 yards greater than the height, and the length of the longer base to be 5 yards greater than the height. For what height will the garden have an area of 360 square yards? Round to the nearest tenth of a yard.17.1 yards
34.2 yards
39.2 yards
152.6 yards

Answers

Correct Answer:
Option A. 17.1 Yards

Solution:
Let the height of trapezium is x yards. According to the given data, we can express the lengths of bases in terms of height.

The short base is 3 yards greater than the height, so measure of short base will be (x+3) yards.

The longer base is 5 yards greater than the height, so measure of longer base will be (x+5) yards.

Area of trapezium is given to be 360 square yards.

Area of trapezium = 0.5 x (Height) x (Sum of Bases)

Using the values, we get:

$360=0.5(x)(x+3+x+5) \n \n 720=x(2x+8) \n \n 2 x^(2) +8x-720=0 \n \n 2( x^(2) +4x-360)=0 \n \n x^(2) +4x-360=0 \n \n x= (-4+- √(16-4(1)(-360)) )/(2) \n \n x= (-4+- √(1456) )/(2) \n \n x = 17.1 , -21.1$

Since the height cannot have a negative value, we conclude that the height of trapezium rounded to nearest tenth of a yard will be 17.1 yards.

Writing to explain Describe a point

Answers

A point is an exact position or location on a plane surface. It is important to understand that a point is not a thing, but a place. We indicate the position of a point by placing a dot with a pencil. This dot may have a diameter of, say, 0.2mm, but a point has no size. No matter how far you zoomed in, it would still have no width. Since a point is a place, not a thing, it has no dimensions. Points are usually named by using an upper-case single letter. Usually represented by a dot.
