Question

Find ∆ADB if parallelogram ABCD is 252cm^2

Answer 1

Answer:

Step-by-step explanation:

If a triangle and a parallelogram lie on the same base and between the same parallels, then ar(triangle)=1/2ar(parallelogram)

In this case, triangle ADB and parallelogram ABCD lie on the same base AB and between the same parallels AB and DC.

Therefore, ar(ADB)=1/2.ar(ABCD)

ar(ADB)=1/2*252

ar(ADB)=126cm
