A square garden with a side length of 150 m has a square swimming pool in the very centre with a side length of 25 m . Calculate the area of the garden.

Area of a Square Problem


AP = 252 = 625 m²

AJ = 1502 − 625 = 21 875 m²

A rectangular garden has dimensions of 30 m by 20 m and is divided in to 4 parts by two pathways that run perpendicular from its sides. One pathway has a width of 8 dm and the other, 7 dm. Calculate the total usable area of the garden.

 

Area of a Rectangle Problem

8 dm = 0.8 m

h = 20 - 0.8 = 19.2 m

7 dm = 0.7 m

b = 30 − 0.7 = 29.3m

AG = 19.2 · 29.3 = 562.56 m²
