Question

The diagram shows Maha's garden.

AB = 15.3 m.
BC= 13.6m.
AD = 24.0m.
Find the perimeter of the garden.​

Answer 1

perimeter = 71.4 m

Explanation:

using the Pythagorean theorem:

CD² = 15.3² + (24 - 13.6)² = 234.09 + 108.16 = 342.25

CD = √342.25 = 18.5

perimeter = 24 + 15.3 + 13.6 + 18.5 = 71.4 m
