a chart paper measures 4 m×3m. astrip of 1 m wide is cutout fromall around .find the area of remaining chart paper and the area of cut out strip
Answers
area of strip cut=4×1 (as all sides are equal so area of square=4m sq.
area of remaining sheet=12-4=8m sq.

Answer:
Step-by-step explanation:
let the rectangle be named as ABCD
AB & CD = 4m
BC &DA = 3m
area of the given chart = L x B
area (it is a rectangle) = 4m x 3m
= 12m²
lengths would be :
- AB & CD = 4 - 1 = 3m
- BC & DA = 3 -1 = 2m
the area of the remaining chart would be = L x B
= 3m x 2m
area = 6m²
area of the strap = area of the whole chart paper - area of the remaining
chart paper
= 12m² - 6m²
= 6m²
I hope so that this must be the answer but am not sure about it.
1m is reduced from each four sides
therefore,
