Answer:

D) 7.5 square units

Step-by-step explanation:

The area of a triangle is found by

A = 1/2 bh

The length of the base is (50) =5

The height is (4-1) =3

A = 1/2(5)(3)

= 15/2

= 7.5

1. A farmer wants to build a fence around a rectangular area of his farm with one side of the region against his barn. He has 76

Arte-miy333 [17]

Answer:

19 ft by 38 feets

Step-by-step explanation:

Given that :

Available fencing = 76 feets

Rectangular fencing with 3 sides

Let the 3 sides be :

x, x, y

x + x + y = 2x + y = 76

y = 76 - 2x

Area = x * y = xy

Area = (76 - 2x) * x

Area = 76x - 2x²

Take derivative of Area with respect to x ; dA

dA /dx = 76 - 4x = 0

76 - 4x = 0

-4x = - 76

x = 76 / 4

x = 19

2x + y = 76

2(19) + y = 76

38 + y = 76

y = 76 - 38

y = 38

Hence, dimension : 19feet by 38 feets

The coordinates of the vertices of a quadrilateral are (8, 11) (11, 7) (8, 3) (2, 3). What is the area, in square units, of the

disa [49]

Check the picture below.

so the quadrilateral is really just a parallelogram below a triangle, so let's simply get the area of each and sum them up.

$\stackrel{\textit{\Large Areas}}{\stackrel{parallelogram}{(6)(4)}~~ + ~~\stackrel{triangle}{\cfrac{1}{2}(6)(4)}}\implies 24~~ + ~~12\implies 36$
