A wall is built of small bricks each of area 100 square cm.
ABCD is a rectangular window in the wall.
On the basis of the measurements of the given wall answer the following questions:
a)What is the area of the wall?
b) What is the breadth of the brick?
c)How many brick are used to make the wall?
Answers
Answer:
Step-by-step explanation:
Q.1) For area of the wall,
length = 50cm, breadth = 80cm
Area of wall = L x B
= 50 x 80
= 4000
Therefore area of wall is 4000sq.cm
Q.2) For breadth of brick,
Area of brick is 100sq.cm
The brick is rectangular
Therefore, area of brick = L x B
100 = L x B
100 = 50 x 2, 25 x 4, 20 x 5, 10 x 10
The breadth can be any as above because there is no definite measurement of length given of the brick.
Q.3) For, no. of bricks,
Area of one brick is 100sq.cm
Area of wall is 4000sq.cm
No. of bricks = Area of wall/Area of bricks
= 4000/100
= 40
Therefore, 40 bricks will be needed to make the wall.
MARK MY ANSWER AS BRAINLIEST
GIVEN
Length of rectangular wall = 50 cm
Breadth of rectangular wall = 80 cm
Area of rectangular window = 100 cm^ 2
EXPLAIN
(i) Area of rectangular wall = L × B
= ( 50 × 80 )cm^2 = 4000 cm^ 2
(iii) Area of each brick = 100 sq. cm
Number of bricks = Area of wall ÷
Area of each brick
= 4000 ÷ 100 = 40
So, 40 bricks are used to make the wall.
Sorry, friend I didn't able to find no. 2
because for finding breadth of the brick
we need length of the brick and the area. The area is given but the length is not given.
