Problem |
The perimeter of a rectangle is 20 meters, and the length of a rectangle is 7 cm. Find the area of the rectangle. |
|
2 |
Step |
The given perimeter of a rectangle is |
20 mtrs |
3 |
Step |
The given length of a rectangle is |
7 mtrs |
4 |
Step |
The perimeter of rectangle formula Now, we have to find the width of a rectangle(W). |
P =2(L + W) |
5 |
Step |
Substitute the values |
20 = 2(7 + W) |
6 |
Step |
Divide 2 on both sides |
\$20/2\$ = \$(2(7 + W))/2\$ |
7 |
Step |
After simplification |
10 = 7 + W |
8 |
Step |
subtract 7 on both sides |
10 - 7 = 7 - 7 + w |
9 |
Step |
Width of the rectangle is |
W = 3 ft |
10 |
Step |
Now, find the area of rectangle by using formula |
A = L * W |
11 |
Step |
Substitute the values |
A = 7 * 3 = 21 |
12 |
Step |
So, the area of the rectangle is 21 sq.ft |
