Answer 1

84cm²

Explanation:

8+7×10 is the total area of the rectangle garden.

To find the area of Lawn, you have to take away the areas of Flower bed and Vegetable Patch

To do so:

Flower bed: (Triangle) 8×4=32, 32÷2=16. 150cm² - 16cm² = 134cm²

Vegetable Patch: (Trapezium) 1/2×( 3+7)×10 = 50cm², 134cm² - 50cm² =84

So, therefore, the area of Lawn is 84cm²
