Answer:
Step-by-step explanation:
To find the breadth use Pythagorean theorem
Breadth² = diagonal² - length²
= 34² - 30²
= 1156 - 900
= 256
Breadth = √256 = 16 cm
Breadth = 16 cm
Perimeter = 2*(length + breadth) = 2*(30 + 16) = 2*46 = 92 cm
Area = length * breadth = 30 *16 = 480 cm²
Step-by-step explanation:
55/12 is your answer
please give me some thanks
Answer:
C, B, A
Step-by-step explanation:
The sides in order from shortest to longest are ...
AB = m-2
AC = m
BC = m+4
The angles opposite these sides will be in order, smallest to largest. The angle opposite is the one whose letter is <em>not</em> in the line segment name.
C, B, A
To help explain how you get A for the answer:
work backwards
5(3a²+11a-4)
multiply everything by 5
5×3a²=15a²
5×11a=55a
5×-4=-20
15a²+55a-20
