Question

I need someone to answer this immediately please. ... The area of a piece of land is 50cm square. Fi d the value of x, if the length

and breadth are given as (x+2) and (x-3)m respectively
options. A. 3
B. 5
C. 7
D. 8​

Answer 1

8

Explanation:

put the 50 under area and continue with like that

Answer 2

x=8

Explanation:

Area is equal to

A = l * w

50 = ( x+2) ( x-3)

FOIL

50 = x^2 -3x+2x -6

Combine like terms

50 = x^2 -x -6

Subtract 50 from each side

0 = x^2 -x -56

Factor

What two numbers multiply to -56 and add to -1

-8*7 = -56

-8+7 = -1

0 = ( x-8) ( x+7)

Using the zero product property

x-8 =0 x+7 =0

x = 8 x=-7

Since the length cannot be negative x cannot be negative

x=8
