A rectangular bedroom has an area of 117 ft. the length of the bedroom is 4ft more than the width. find the length and the width
MrMuchimi

Answer: Length = 13 ft. , Width = 9 ft.

Step-by-step explanation:

Rectangle area = Length x width

Area = 117 ft.

Length = x + 4

Width = x

To solve

(x)(x + 4) = 117

x^2 + 4x = 117

x^2 + 4x - 117 = 0

(x - 9)(x + 13)

x = 9, -13

x = 9 <em>(measurement cannot be negative)</em>

Length

x + 4

9 + 4 = 13

What is the volume of a regular pyramid having a base area of 24 in.² and a height of 6 inches?
Assoli18 [71]

Answer:

48 in³

Step-by-step explanation:

The volume (V) of a pyramid is calculated as

V = \frac{1}{3} × area of base × height

here area of base = 24 and height = 6, so

V = \frac{1}{3} × 24 × 6 = 8 × 6 = 48 in³
