Question

sum of the area of two sqares is 640 sqm. If the difference between the perimeter of the sqares is 64m find the length of the sqares

Answer 1

hi!!!!!!!!

Sum of the area of two squares is 640

=> x+y=640 sq. m. -------(1)

Difference between the perimeter of the squares is 64

=> x-y=64 cm. --------(2)

from (1)&(2)

x+x+y-y=640+64
2x =704
x =704/2
x =352

substitute x values in both equation(1)

x+y=640
352+y=640
y=640-352
y=288

x=352 and y=288
