Question

QUESTION 1 1.1 Give the formula for the area of the following figures: 1.1.1 a square (3) 1.1.2 a rectangle 1.1.3 a triangle 1.2 Determine the area of the square ABCD with AB=3cm. А D с (3)​

Answer 1

Explanation:

Area of a square 1.1.1=

`{l}^(2) = l * l`

Area of a rectangle 1.1.2=

`l * b`

Area of a triangle 1.1.3=

`(1)/(2) * base * height`

Area of square ABCD

`|ab| = 3cm`

Area of a square =l×l

l=3cm

Area = 3×3=9cm2
