Jeffrey drew a square field.
The length of the square field is 20 m.
Now he increased the length by 5.
So the new length is 20 + 5 = 25 m.
He also decreases the width by 5 m.
Hence the new width shall be 20 - 5 = 15 m.
The formula for the area of the rectangle is
= length × width
= 25 × 15
= 375 m²
The area of the rectangle after increasing the length by 5 m & decreasing the width by 5 is 375 m².
