Question

The length of a rectangle exceeds the width by 7cm. If the area is 60cm2 , find the length of the rectangle

Answer 1

Answer:

length= 30 cm

Step-by-step explanation:

..........

Answer 2

solution;

let , the width of rectangle = X

and length of rectangle = (x+7)

given ;

area of rectangle is =

$60cm ^{2}$

now;

area of rectangle = length × breadth

$60cm ^{2} = x ( \times + 7) \\ \\ 60cm ^{2} = x ^{2} + 7x \\ \\ x ^{2} + 7x - 60$

now split to find

(x+12)(x-5)

x= -12, x= 5

breath can never be -ve

so the , value of x= 5

length of rectangle = (x+7)

= 5+7

length =12
