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?

Respuesta :

We have

A=7632m^2

the formula of the area of a rectangle

[tex]A=l\times w[/tex]

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

[tex]7632=99\times w[/tex]

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

[tex]\frac{99}{99}\times w=\frac{7632}{99}[/tex]

[tex]w=\frac{7632}{99}=77.09m[/tex]

the width is 77.09m
