Question

the area of Garden is X square + 4 x - 221 unit square if the width of the field is x minus 13 units find its length​

Answer 1

Answer:

x + 17

Step-by-step explanation:

Gn:

area = x² + 4x - 221

b = x - 13

To find : length (l)

l * b = area

l * (x - 13) = x² + 4x - 221

l * (x - 13) = x² + 17x - 13x - 221

l * (x - 13) = x (x + 17) -13 (x + 17)

l * (x - 13) = (x - 13) (x + 17)

l = (x + 17)

therefore, the length = x + 17
