Question

a)The area of a rectangular field is 7632m² .If the length of the field is 99 m, what is its width?b) The perimeter of a rectangular painting is 358 cm. If the width of the field is 82 cm, what is its length?

Answer 1

We have

A=7632m^2

the formula of the area of a rectangle

`A=l* w`

where l is the length and w is the width

in our case we have

l=99m

then we substitute the values given in the formula

`7632=99* w`

we need to isolate the w in order to find the value of the width

`(99)/(99)* w=(7632)/(99)`

`w=(7632)/(99)=77.09m`

the width is 77.09m
