Find below the list of all AP Board Class 7th Maths Chapter 13 Area and Perimeter Ex 4 Textbook Solutions for PDF’s for you to download and prepare for the upcoming exams:Question 1.
Find the area of the following rhombuses.
Solution:
Area = 12d1d2
d1 = 5 + 5 = 10cm
d2 = 2 + 2 = 4cm
A = 12 × 10 × 4 = 20 cm2
d1 = 3 + 3 = 6 cm
d2 = 4 + 4 = 8cm
Area = 12d1d2
= 12 × 6 × 8
= 24 cm2
Question 2.
Find the missing values.
Diagonal – 1 (d1) | Diagonal – 2 (d2) | Area of the rhombus |
12cm | 16cm | |
27mm | 2025mm2 | |
14m | 57.6m |
Solution:
Diagonal – 1 (d1) | Diagonal – 2 (d2) | Area of the rhombus |
12cm | 16cm | 12 × 12 × 16 = 96cm2 |
27mm | 2025×227 = 150mm | 2025mm2 |
14m | 57.6m | 12 × 24 × 57.6 = 691.2 m2 |
Question 3.
If length of diagonal of a rhombus whose area 216 sq. cm. is 24 cm. when find the length of second diagonal.
Solution:
Given: Length of one diagonal d1 = 24cm, d2 =?
Area = 12d1d2 = 216
12 × d1 × d2 = 216
12 × 24 × d2 = 216
d2 = 21612 = 18
Question 4.
The floor of a building consists of3 000 tiles which are rhombus shaped. The diagonals of each of the tiles are 45 cm and 30 cm. Find the total cost of polishing the floor, if cost per m2 is Rs.2.50.
Solution:
Diagonals of each (shape / rhombus) tiles
d1 = 45cm, d2 = 30cm
Total tiles = 3000
Total area = 3000 × Area of each tile = 3000 × 12 × d1 × d2
= 3000 x 12 × 45 × 30 = 2025000 cm2
= 2025000100×100 m2 = 202.5m2
∴ Cost of polishing the floor at the rate of Rs. 2.50 per a square metre 202.5 × 2.50 = Rs. 506.25
