Question

the sides of rectangular piece of paper are in the ratio 2 : 3. If the area is 150 square sq cm find the length of its sides?​

Answer 1

Answer Will be 10cm and 15cm

we have given the ratio of the sides of rectangle i.e., 2:3
let the common ratio be k
therefore, the sides will be 2k and 3k
also, we have given the area of rectangle i.e., 150 cm square
we know that area of rectangle = l×b
therefore, 150=2k×3k
150=6k^2
25=k^2
5=k
therefore,
2k=5×2=10
3k=5×3=15
