Step-by-step explanation:
length of remaining wooden pice
Given : Roma gave a wooden piece of length 12 1/4 m and breadth 5 1/2 m to a carpenter for making a shelf. The carpenter sawed off a piece of length 4 1/2 m from it
To Find : length of the remaining piece
the breadth of the remaining piece
area of remaining piece
perimeter of the remaining piece
Solution:
Length = 12 1/4 = 49/4 m
Breadth = 5 1/2 = 11/2 m
The carpenter sawed off a piece of length 4 1/2 m from it = 9/2 m
length of the remaining piece = 49/4 - 9/2 = (49 - 18) /4 = 31 /4
= 7 3/4 m
breadth of the remaining piece 5 1/2 m as nothing cut from breadth
Area of remaining = length * breadth
= ( 31 / 4)(11/2)
= 341 / 8
= 42 5/8 m²
Perimeter = 2 (length + breadth)
= 2 ( 31/4 + 11/2)
= 2(31 + 22)/4
= 53/2
= 26 1/2 m
