Question

A 10 ft by 10 ft square garden contains a large walking path through the diagonal what is the area of the walking path shown in the grey above

Answer 1

64 ft^2

Explanation:

Area of shaded part = area of a square = 2 x area of a triangle

area of a square = length^2

10^2 = 100 ft^2

Area of a triangle = (1/2) x base x height

1/2 x 6 x 6 = 18 ft^2

area of shaded part = 100 - 2x 18 = 64 ft^2
