inysia [295]

Answer:

The correct answer is,

the area of given triangle = 1875 square feet

Step-by-step explanation:

Formula:

Area of triangle = bh/2

b - Base and h - height

It is given that,a triangle with a base of 50 feet and a height of 75 feet’

<u>To find the area of triangle</u>

base b = 50 feet and height h = 75 feet

Area = bh/2 = (50 x 75 )/2

Area = 3750/2 = 1875 square feet

Therefore the area of given triangle = 1875 square feet

A fence is being built around a rectangular garden. The length of the garden is 35 feet, and the total fencing used to enclose t

liraira [26]

The garden's width is 45. We know this because
$35 \times 2$
(length)
$35 \times 2 + 2x = 160 \\$
35x2 is 70 and you need to neutralize that by taking away 70 from both sides.
$160 - 70 = 90$
$2x = 90$
Now divide by 2 on both sides to neutralize the 2 times x.
$90 \div 2 = 45$
meaning that leaves us with
$x = 45$
