Answer: 120m
Step-by-step explanation:
Width = 20m
Length = 2 × width
= 2 × 20m
= 40m
We've to calculate the perimeter
Perimeter = 2(length + Breadth)
= 2(20m + 40m)
= 2(60m)
= 120m

Answers:
∠A=45° & ∠B=45°
Step-by-step explanation:
In triangle ABC, all angles are less than 180° but their sum is 180°
For the trigonometric statements
sin(A)=cos(B)
sin(B)=cos(A)
These are true when these angles that are A and B are equal and on these angles the sin and cos value must be same.
Hence, both angles are of 45°
