Answer:
7.28 m
Explanation:
Use the Pythagorean Theorem. The length of the ladder is the hypotenuse.
a^2 + b^2 = c^2
a = 2, b = 7, c = ?
Plug in the values into the equation.
2^2 + 7^2 = c^2
4 + 49 = c^2
Square root both sides to get c = 7.28
Answer:
Option a, (x-26)x
Step-by-step explanation:
Length is 26 units less than its width, let the length be x, so the width is x+26, so it's area will be their multiplication,
x(x+26)
since the formula to find area is (length×width)
However thing to note, if you assume the width to be x, the the length will be (x-26), so here the area becomes (x-26)x
since here the length is less than width, (x-26)x is the answer we will use.
