A rectangle has an area of 96 cm2 The length of the rectangle is 4 cm longer than the width. Work out the length and width of th

Svetach [21]

Area of a rectangle: 2(L+W)
length: 4+W

Area: 2(4+W) + 2W = 96
8+2W+2W = 96
8+4W = 96
4W = 88
W= 22cm

Calculate for length: 2L + 2(22) = 96
2L + 44 = 96
2L = 52
L = 26cm

• The length is 26cm and width is 22 cm.

worty [1.4K]

Answer:

9.2 bookcases

Step-by-step explanation:

Let X be the number of bookcases repainted.

-Given the available paint is 4 3/5 gallons and that each bookcase consume 1/2 gallon, we equate and solve for X:

$X=\frac{P_t}{P_b_c}, P_t=4\frac{3}{5}, P_{bc}=\frac{1}{2}\\\\\\X=\frac{4\frac{3}{5}}{\frac{1}{2}}\\\\X=9\frac{1}{5}$

Hence, the number of bookcases repaind is 9.2
