A square patio has an area of 215 square feet. How long 4 Jan 2016 · "14.65 ft" The area of a square can be found through the equation A=s^2 where A is the area and s is the length of any side. Since A=215, we can say that 215=s^2 To find just s, take the square root of both sides. s=sqrt215 Plug this into a calculator. s=sqrt215approx14.65
The base of a triangular garden is 5 yards longer than the 7 Nov 2017 · height= 16 yards base = 21 yards Let the height of the triangular shaped garden be h yards. Its base would then be 5+h yards. Formula for the area of any traingle is 1/2 base X height. By this formula, 1/2 (5+h) Xh= 168 On simplifying this. h^2 +5h =336 Or h^2 +5h-336=0. Now factorise this quadratic expression by splitting the middle term, keeping in view the fact that …
The length of a rectangular garden is 3 yd more than twice 10 Feb 2016 · Write an equation to represent the situation Assuming 2x + 3 represents the length and x represents the width. 2x + 3 + x + 2x + 3 + x = 36 6x + 6 = 36 6x = 30 x = 5 The width measures 5 yards and the length 13 yards. Hopefully this helps!
A mixture of concrete is made up of sand and cement in a 12 Nov 2016 · 80 cubic feet of sand and 100 cubic feet of cement If the components of concrete are in the ratio 4:5, it means that the mix can be considered as consisting of 9 parts. The fraction of each is: Sand = 4/9" and " cement = 5/9 Therefore in 180 cubic feet: Sand = 4/9 xx 180 = 80 cubic feet. Cement = 5/9 xx 180 = 100 cubic feet
