Question

If the sides of a share are increased by the 3 m, the area becomes 64 m squared. Find the length of a side of the original square.

Answer 1

The original length of a side was 13m

I got this by

taking 3m and * it by 4 because thats how many sides there are then

I got 12 so I subtracted 12 from 64 i got 52

so i divided the 52 by 4

which is

13
