Area of a triangle = (b·h)/2
the base would be the diameter of the circle, so 4+4=8 ft, the height is 10 ft.
A= (4×10)/2
A=20 ft²

Answer:
First Picture: Length = 30.82in
Second Picture: Length = 34.64in
Step-by-step explanation:
Given
Picture 1:
Area = 950in²
Picture 2:
Area = 1200in²
Required
Determine the length of each pictures
From the question, we understand that both pictures are square in shape and the area is calculated as thus:
Area = Length²
For the first picture, substitute 950 for Area
This gives:
950 = Length²
Length ² = 950
Take square root of both sides
Length = √950
Length = 30.8220700148448822
Length = 30.82 (approximated)
Hence, the length of the first picture is 30.82in
For the second picture, substitute 1200 for Area
This gives:
1200 = Length²
Length² = 1200
Take square root of both sides
Length = √1200
Length = 34.6410161513775458
Length = 34.64 (approximated)
Hence, the length of the second picture is 34.64in
No, Alex is wrong. The correct expanded form would be 100+60+5+.03+.008
