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

Step-by-step explanation:

Area of a square 1.1.1=

${l}^{2} = l \times l$

Area of a rectangle 1.1.2=

$l \times b$

Area of a triangle 1.1.3=

$\frac{1}{2} \times base \times height$

Area of square ABCD

$|ab| = 3cm$

Area of a square =l×l

l=3cm

Area = 3×3=9cm2
