Answer:
surface area of the square pyramid
=(32×32)+(2×32×20)
=1024+1280
=2304 square feet
Answer:
Step-by-step explanation:
15x - 10 = 10 + 6 + 2x
15x - 10 = 16 + 2x
Bringing like terms on one side
15x - 2x = 16 + 10
13x = 26
x = 26/13
x = 2
Jeffrey drew a square field.
The length of the square field is 20 m.
Now he increased the length by 5.
So the new length is 20 + 5 = 25 m.
He also decreases the width by 5 m.
Hence the new width shall be 20 - 5 = 15 m.
The formula for the area of the rectangle is
= length × width
= 25 × 15
= 375 m²
The area of the rectangle after increasing the length by 5 m & decreasing the width by 5 is 375 m².
