Answer:
dx/dt = 5√5/2
Step-by-step explanation:
Given:
dx/dt = 25 feet per second
According to Pythagoras theorem:
x² + 90² = y²
We know that x = 30 ft
So,
x² + 90² = y²
30² + 90² = y²
y = 30√10
So,
x² + 90² = y²
By taking differentiate:
2x dx/dt = 2y dy/dt
[x/y][dx/dt] = dy/dt
dx/dt = 5√5/2
To find the area of a rectangle, just multiply the dimensions.
36
x60
00
360
1800
2160
The area of the rectangle is 2,160 in sq

Answer:
a. 140 in²
Step-by-step explanation:
Find the area of triangle
1/2×10×6 = 30
The area of rectangle
10×11 = 110
Total of area = 30 + 110
= 140 in²
