Answer:
Perimeter=60.18cm
Area=215.495cm^2
Step-by-step explanation:
Given:
Length of book=18.34cm
Breadth=11.75cm
Solution:
Perimeter=2(l +b)
P=2(18.34+11.75)
P=2 x 30.09
P=60.18cm
Area=l x b
A=18.34 x 11.75
A=215.495 cm^2
Thank you!

Answer:
D. 500 J
Step-by-step explanation:
We are given;
- Force applied as 50 Newtons
- Distance moved as 10 meters
We are required to determine the work done
We need to know the formula for calculating the work done
That is; Work done = Force × Distance
Work done is the product of force and the distance covered.
It is measured in joules
In this case;
Work done = 50 N × 10 m
= 500 joules
Thus, the work done 500 joules
