Question

A rectangle field having dimension 50m x 40m has been fenced with a wire. If the same

wire is re-used completely to fence a square field, then find the measure of a side of the

square field.​

Answer 1

so we have to find perimeter of rect.

2(L+B)=2X(50+40)

=2X90

=180 m

SO WIRE IS REUSED IN SQ. FIELD

SO THAT PERIMETER OF RECT=PERIMETER OF SQ.

180=4X (SIDE = X)

180/4=X

so x =45 m
