Question

Please help area and perimeter of functions

Answer 1

Answer:

= 150 square units

Step-by-step explanation:

Area of a right triangle is given by the formula;

1/2 bh ; where b is base and h is the height of the triangle

using Pythagoras  theorem, we can find the height;

h² = 20² - 16²

h = √144

  = 12 units

The base of the small triangle can also be found using Pythagoras theorem;

b² = 15² - 12²

b  = √ 81

   = 9

Therefore;

Area = 1/2 bh

        = 1/2 × 12 × (16+9)

        = 1/2 × 12 × 25

        = 6 × 25

        = 150 square units or 150 u²
