Answer:
Step-by-step explanation:
1) length = x m
breadth = x/2 m
Area of rectangular floor = 32 square m
![length * breadth = 32\\\\x*\dfrac{1}{2}x = 32\\\\\\x^{2}=32*2\\\\\\x^{2} = 64\\\\x=\sqrt{64}=\sqrt{8*8}\\\\x = 8 \ m](https://tex.z-dn.net/?f=length%20%2A%20breadth%20%3D%2032%5C%5C%5C%5Cx%2A%5Cdfrac%7B1%7D%7B2%7Dx%20%3D%2032%5C%5C%5C%5C%5C%5Cx%5E%7B2%7D%3D32%2A2%5C%5C%5C%5C%5C%5Cx%5E%7B2%7D%20%3D%2064%5C%5C%5C%5Cx%3D%5Csqrt%7B64%7D%3D%5Csqrt%7B8%2A8%7D%5C%5C%5C%5Cx%20%3D%208%20%5C%20m)
Length = 8 m
Breadth =8/2 = 4 m
Perimeter = 2*(length + breadth) = 2*(8 + 4)
= 2*12
= 24 m
2) Perimeter of square = 12 cm
Side of a square = perimeter ÷ 4 = 12 ÷ 4 = 3 cm
Area =side *side = 3*3 = 9 cm²
3) Perimeter of square field = 60 m
Side = Perimeter ÷ 4 = 60 ÷4 = 15 m
Area of square = 15 * 15 = 225 m²
4) Perimeter of rectangle = 28 cm
breadth = (Perimeter ÷ 2) - length
= (28 ÷2) - 8
= 14 - 8
Breadth = 6 cm
Area of rectangle = 8 * 6 = 48 cm
What are the answer choices in the drop down?
Answer:
51m
Step-by-step explanation:
tan 21 = y/35; y=13.43
tan 47 = x/35; x=37.53
13.43+37.53 = 50.97 = 51m
Perpendicular bisectors would intercept inside the triangle. A perpendicular bisectors is a line that bisects each side of the triangle and is perpendicular to it, so if you picture it in you head, you can see that they intercect inside the triangle.
