The width of a rectangle is 5 centimeters less than the length . The area of the rectangle is 36 centimeters.find the length?
Answer:
9 centimeters
Step-by-step explanation:
Let the width be represented by l - 5, where l is the length.
Use the area formula, A = lw, and plug in l - 5 as w, and 36 as the area. Then, simplify and factor
A = lw
36 = l(l - 5)
36 = l² - 5l
0 = l² - 5l - 36
Factor:
(l - 9)(l + 4)
Set equal to zero and solve for both solutions:
(l - 9)(l + 4) = 0
l - 9 = 0
l = 9
l + 4 = 0
l = -4
The length cannot be negative, so the answer has to be 9.
The length is 9 centimeters

Randy wants to install a patio, which will be filled with concrete. The dimensions of the patio are 14 m long, 8 m wide, and 1 m deep. Determine the cost of the
concrete to be used while installing the patio if the concrete is available to Randy at the rate of $5 per cubic meter.
The cost of the concrete for installing the patio will be,
Answer:
Total cost of patio = $560
Step-by-step explanation:
Given:
Length of patio = 14 m
Width of patio = 8 m
Height of patio = 1 m
Cost of 1 m³ concrete = $5
Find:
Total cost of patio
Computation:
Volume of patio = l x b x h
Volume of patio = 14 x 8 x 1
Volume of patio = 112 m³
Total cost of patio = Volume of patio x $5
Total cost of patio = 112 x $5
Total cost of patio = $560

Answer:
b = 2.8253A = 45.2°C = 107.4°Step-by-step explanation:
The given sides form the given angle, so the Law of Cosines can be used to find the third side.
b = √(a² +c² -2ac·cos(B)) ≈ √7.982544072 ≈ 2.8253
The measure of angle A can be found from the Law of Sines.
A = arcsin(a/b·sin(B)) ≈ arcsin(0.71017) ≈ 45.2°
Angle C can be calculated from the other two angles.
C = 180° -27.4° -45.2° = 107.4°
