If the triangle is increased to twice the base and the height the size will increase by 48 ft²

<h3>How to find the area of a triangle?</h3>

The area of a triangle can be described as follows;

area of a triangle = 1 / 2 bh

where

  • b = base
  • h = height

Therefore, the total area of the garden is 16 square feet.

Hence,

16 ft² = 1 / 2 bh

Hence, if the the triangle is increased to twice the base and the height the size will be as follows;

area = (1 / 2) × 2b × 2h

area = 4 × (1 / 2 bh)

area = 4 × 16

area = 64 ft²

Therefore,

difference in area = 64 ft² - 16 ft²

difference in area = 48 ft²

Therefore, if the the triangle is increased to twice the base and the height the size will  increase by 48 ft²

0.08(507)

Step-by-step explanation:

Here, we want to select the part of the expression that represents the amount of tax Deborah has to pay

From the expression, we have ;

0.08(507) + 50h

Kindly note that we can have 0.08 as 8/100

8/100 is same as 8%

when we represent taxes, it is usually a percentage of something

In that case, the tax part would be ; 0.08(507)
