Question

If the length and breadth of a triangle are 10cm and 8cm respectively. Find its perimeter if the length and breadth are doubled

Answer 1

Answer:

the perimeter is 72cm

length = 10cm

then the double of length is = 20cm

breadth = 8cm

so the double of breadth is = 16cm

so the perimeter = 2(20+16) = 72cm
