Question

Answerrrrrr pleaseeeeeee

Answer 1

A=height*base/2

A=(9-6)*(5-2)/2

A=3*3/2

A=4.5cm^2 answer=(a)

Answer 2

16.5 cm²

Explanation:

The area (A) of a triangle is calculated using the formula

A =
`(1)/(2)` bh ( b is the base and h the perpendicular height )

In large triangle b = 5 and h = 9, hence

A =
`(1)/(2)` × 5 × 9 = 22.5 cm²

In small triangle b = 2 and h = 6, hence

A =
`(1)/(2)` × 2 × 6 = 6 cm²

Difference in areas = 22.5 - 6 = 16.5 cm²
