What is a rectangle?

"A rectangle has two pairs of equal opposite parallel sides, four right angles and two diagonals. The diagonals of a rectangle are congruent.

They also bisect each other. Each diagonal divides the rectangle into two congruent right triangles."

Given

A rectangle is divided into 25 equal parts.

Number of parts must be shaded in order to cover three fifths of the rectangle

= $\frac{3}{5}$ × $25$

= 15

Checking whether the 15 parts must be shaded in order to cover three fifths of the rectangle

= $\frac{15}{25}$

= $\frac{3}{5}$

Hence, 15 parts must be shaded in order to cover three fifths of the rectangle.
