Answer»

Area of the square=14²=296 cm²

Two semicircles are inscribed in the square with its opposite sides as their respective diameters.

Sum of area of the semicircles=2×(πr²/2)=πr²=3.14×7²=153.86 cm²≈154 cm²

∴Area of the shaded portion=Area of the square-Area of both the semicircles=( 296-154 ) cm²=142 cm²
