Learning Task 3
inches.
is each side of this picture?
1. How long is each side of the picture?
Answers
Answer:
For first square picture
As it is square type picture so , Area = side²
Area of picture = 950
Let side of picture be a
Now,
Area = 950
a² = 950 •(Area = side² = a²)
a=√950
a=30.8 units
So length of first square picture is 30.8 units
For another square picture
As it is square type picture so , Area = side²
Area of picture = 1200 sq.inches
Let side of picture be b
Now,
Area = 1200
b² = 1200 •(Area = side² = b²)
b= √1200
b= 34.64 inches
So length of first square picture is 34.64 inches
Thanks please follow and like if you got help
Given : square pictures
Area = 950 inch²
Area = 1200 inch²
To Find : Length of each side of picture
Solution :
Each side of Square are equal
Area of Square = Side length²
Hence Side length = √Area
Side of Area 950 inch² = √950
