Answer 2

Area Of Figure = 77.25 m²

Step-by-step explanation:

GIVEN

Sides Of Square = 9 m

Base Of Triangle = 2.5 m

Height Of Triangle = 3 m

___________________________

TO FIND

Area Of Figure

___________________________

We know that,

Area Of Triangle = ½ × Base × Height

Area Of Triangle = ½ × 2.5 × 3

Area Of Triangle = ½ × 7.5

Area Of Triangle = 3.75

Area Of Triangle = 3.75 m²

___________________________

We know that,

Area Of Square = Side × Side = Side²

Area Of Square = 9³

Area Of Square = 81

Area Of Square = 81 m²

___________________________

We know that,

Area Of Figure = Area Of Square - Area Of Triangle

Area Of Figure = 81 - 3.75

Area Of Figure = 77.25

Area Of Figure = 77.25 m²
