Find surface area of -

Answer 1

144 units²

✔️Area of rectangle 1 = L*b

L = 11

b = 3

Area of rectangle 1 = 11*3 = 33 units²

✔️Area of rectangle 2 = L*b

L = 11

b = 4

Area of rectangle 2 = 11*4 = 44 units²

✔️Area of rectangle 3 = L*b

L = 11

b = 5

Area of rectangle 3 = 11*5 = 55 units²

✔️Area of the two triangles = 2(½*ba se * height)

ba se = 4

height = 3

Area of the two traingles = 2(½*4*3)

= 12 units²

✔️Surface area of the right triangle = area of rectangle 1 + area of rectangle 2 + area of rectangle 3 + area of the two triangles

= 33 + 44 + 55 + 12

= 144 units²
