Question

Area of square p ,q are in the ratio 4:9 if p 144 then find the perimeter of q

Answer 1

Given data is P/Q =4/9 and P=144 sq cm…. Now..144/Q =4/9 implies Q=144×9/4 therefore Q=36×9=324…..perimeter of a square of side length a is equal to 4a. We find Q area is 324 sq cm..i.e a^2=324 implies a=18 and perimeter =4×18=72 cm.
