Question

perimeter of a rectangle whose sides
are in the reatio 3:2 is 275 m. Find
its area.​

Answer 1

Step-by-step explanation:

let x be constant.....

first side = 3x and another side = 2x

perimeter = 275

2(l+b) = 275

2(3x+2x) = 275

10x = 275

x = 27.5 cm

first side = 3x = 3(27.5) = 82.5 cm

another side = 2x = 2(27.5) = 55 cm

Area = l×b

= 82.5 × 55

= 4537.5 sq cm
