The lenght of one side rectangle is x cm the length of longer side is (X+4) cm if the rectangle has the peimeter of 48 cm find the area?

140cm²

Step-by-step explanation:

Perimeter of a rectangle is calculated as: = 2(length + width)

where,

Length = x+4

Width = x

Therefore, perimeter = 2(length + width)

2(x + x+4) = 48

2(2x + 4) = 48

4x + 8 = 48

4x = 48 - 8.

4x = 40

x = 40/4

x = 10cm

The other side = x+4 = 10+4 = 14cm

Area = length × width

Area = 10cm × 14cm

Area = 140cm²

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
