Question

the width of a rectangular garden is 6 meter less than the length of the length of the garden. if the area of the garden is 78 square meters . what are the dimensions of the dimensions of the nearest tenth of a meter

Answer 1

Let's assume

width =w

length=l

we are given

The width of a rectangular garden is 6 meter less than the length of the length of the garden

so, we have

`w=l-6`

we know that

Area = length*width

`A=l*w`

we are given

the area of the garden is 78 square meters

so, we can set A=78

`78=l*w`

now, we can plug for w

`78=l*(l-6)`

`l^2-6l-78=0`

now, we can solve for l

we get

`l=12.3`

now, we can find w

`w=12.3-6`

`w=6.3`

so, dimensions are

length is 12.3m

width is 6.3m................Answer
