Four congruent isosceles right triangles are cut from the 4 corners of a square with a side of 20 units. The length of one leg of the triangles is equal to 4 units. What is the area of the remaining octagon?
Answers
Answer:
368 sq. units.
Step-by-step explanation:
We have a square of side lengths 20 units and we cut four congruent isosceles right triangles from the corners of the square.
Now, the four isosceles right triangles have one leg equal to 4 units.
Therefore, the area of four triangles = sq. units.
Now, we have the area of the given square is (20 × 20) = 400 sq. units.
Therefore, the area of the remaining octagon will be (400 - 32) = 368 sq. units. (Answer)

we know that
Two angles are supplementary if the sum of their angles is equal to 180 degrees
and
Two angles are complementary if the sum of their angles equals 90 degrees
so
if an angle measures °
then
Angle Supplementary=
Angle Supplementary=°
Angle Complementary=
Angle Complementary=°
90-47=43 degrees
Supplementary equal 180 degrees.
180-47=133 degrees

1.2 Multiply (3-2p) by (3-2p)
The rule says : To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (3-2p) and the exponents are :
1 , as (3-2p) is the same number as (3-2p)1
and 1 , as (3-2p) is the same number as (3-2p)1
The product is therefore, (3-2p)(1+1) = (3-2p)2
