the perimeter of two square are 848cm and 436cm find the perimeter of square whose area is equal to the sum of areas of two square.

1 answer

each side of first one is 848/4 or 212 cm
each side of the 2nd is 436/4 or 109 cm

so the area of the first = 212^2 cm^2 = 44944 cm^2
the area of the 2nd is 109^2 cm = 11881 cm^2
total area = 56825 cm^2
each side is √56825 = 5√2273
and the perimeter = 20√2273
= appr 953.52
