Answer:
possibly 145 ?
Step-by-step explanation:
minus 25 from 170
ABPQ is a square and ADP and BQC are two triangles.
It is a quadrilateral that has one pair of parallel sides and a height.
The area is calculated as: 1/2 x sum of the parallel sides x height.
Examples:
Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.
Area = 1/2 x (3 + 4) x 5
Area = 1/2 x 7 x 5
Area = 35/2 = 17.5 cm^2
We have,
Here's a diagram of how to draw two lines to make a square and two triangles in a trapezoid:
A___________B
/ | | \
/ | | \
/ | | \
D __P_________Q____ C
To make a square andthe two triangles, draw a line from point A to P and from point B to Q.
Now,
We see that,
ABPQ is a square and ADP and BQC are two triangles.
Thus,
ABPQ is a square and ADP and BQC are two triangles.
