Question

Hi can you help me with this question

Answer 1

68 m²

Explanation:

The area of the lawn is calculated as

area of garden - area of flower bed - area of vegetable patch

Calculating the area of each

area of rectangular garden = 14 × 10 = 140 m²

area of flower bed =
`(1)/(2)` × 3 × 8 = 12 m²

area of vegetable patch =
`(1)/(2)` × 10 × (5 + 7) = 5 × 12 = 60 m²

Thus

area of lawn = 140 - 12 - 60 = 68 m²
