Question

The base and corresponding altitude of a parallelogram are 10cm and 12cm respectively. If the other alritude is 8cm, find the length of the other pair of parallel sides

Answer 1

Here given : b=10cm ,h=12cm

then as we know that

Area of llgm= b*h
=10*12=120cm^2



and if it's altitude is 8 cm the. as we know sides of llgm are equal means =b


area of llgm=b*h=120
b*8=120
b=120/8=15

so parallel sides are 15 cm and 15cm
