Answer 1

area of the figure = 61 m²

Explanation:

figure has 1 rectangle and two triangles

area of rectangle = length * width

= 3 * 11 = 33 m²

area of triangle 1 = 1/2 * base * height

= 1/2 * 4 * 7 = 14 m²

area of triangle 2 = 1/2 * base * height

= 1/2 * 4 * 7 = 14 m²

thus, area of figure = area of rectangle + area of triangle 1 + area of triangle 2

= 33 + 14 + 14 = 61 m²
