Answer:

<h2>7m  x  4m</h2>

Step-by-step explanation:

Area of a rectangle (A) = L * W -----1

Perimeter (P) = 2L + 2W     ----------2

where:

A = 28 sq. m.

P = 22 m.

we can use either formula 1 or 2 to get L or W

say

A = L * W

28 = L * W

L = 28 / W

substitute L = 28 / W  into formula 2

P = 2L + 2W

22 = 2(28 / W) + 2W  then multiply  W on each side

22W = 56 + 2W²

solve W using quadratic equation:

W = 7 and W = 4

therefore

the dimension of the garden is: 7m  x  4m

VladimirAG [237]
Cross section is the area you make when you make a cut across a shape. In this case, the cut must be parallel to the base. Hence, the cut shape would be same to that of the base. The base's dimensions are 7 cm long x 5 cm wide. Thus, the cross section area is 35 square centimeters.

For a class experiment, Danny's class weighed a log before and after subjecting it to termites. Before subjecting it to termites
m_a_m_a [10]

Answer:

4.75 pounds

Step-by-step explanation:

Before the termites: 5 pounds

After the termites: 1/4 of a pound

Amount that the termites took: x

5 - x = 1/4

Add x to both sides of the equation

5 = 1/4 + x

Subtract 1/4 from both sides of the equation

4 3/4 = x

4 3/4 = 4.75

The termites took 4.75 pounds from the log

Hope this helps :)
