Answer:
SEE BELOW
Step-by-step explanation:
Since, △ABC is a right angled triangle. We can apply Pythagoras' Theorem to find the length of AB.
According to Pythagoras’ theorem, “In a right angled triangle: The square of the hypotenuse is equal to the sum of the squares of the other two sides.”
Applying Pythagoras’ theorem in △ABC, we get
AB2=AC2+BC2
⇒AB2=52+122
⇒AB2=25+144
⇒AB2=169
⇒AB=169−−−√
⇒AB=13 cm
Answer:
The chalkboard costs $54.00
Step-by-step explanation:
A chalkboard is in a shape of a rectangle. The chalkboard mentioned measures 1 meter by 2 meters.
The area of a rectangle is given by the formula:
A = lw
Use formula:
A = (2)(1) = 2 m^2
The chalkboard costs $27.00 per square meter so:
2 x 27 = 54
The chalkboard costs $54.00
