PQRS is a trapezium having PS and QR as parallel sides. A is any point on PQ and B is a point on SR such that AB||QR. If area of ΔPBQ is 17 cm2, find the area of ΔASR.
Given that,
Area ( = 17 cm2
PQRS is a trapezium
PS ‖ QR
A and B are points on PQ and RS respectively
AB ‖ QR
We know that,
If a triangle and a parallelogram are on the same base and between the same parallels, the area of triangle is equal to half area of parallelogram
Here,
Area ( = Area (
(i)
Area ( = Area (
(ii)
We have to find Area (,
Area ( = Area (
+ Area (
= Area ( + Area (
= Area (
= 17 cm2
Hence,
Area ( is 17 cm2.
