Question

Two rectangle ABCD and PQRS are congruent. If the length of the rectangle ABCD is 15m and its perimeter is 50m, find the length and breadth of rectangle PQRS?
​

Answer 1

perimeter of ABCD is 2(L+B)

50 = 2(15+b)

B=10m

both the triangle are congruent than it's perimeter and length and breadth are equal so, perimeter of pqrs is 50m and L=15 m, B= 10 m
