What is the area of a rectangle with the length of 8 m and the height of 500 cm?
area of rectangle = l * b area = 8 * 5 =40 m ^2 ( 1 m=100 cm 500cm= 5 m)
Is 2 m greater than or less than 265 cm?
No. 2m is only 200cm.
The length of the scale model of the hall is 95 cm Work out the real length of the hall Give your answer in meters?
as this question is continuation of another question....so usin results of previous question that is 12m = 1200 cm 1200cm / 30 cm = 40 1:40 so we can write 95cm * 40 = 3800 cm 3800 cm = 38 m (which is the required answer) by Hanny Tufail hanny.tufail@gmail.com
Is 536 cm greater or smaller than 53.6 m?
It is smaller, as it is only 5.36m, so it is 10 times smaller.
Does any obtuse triangle have a greater area than any acute triangle?
No.Finding an obtuse triangle that does not have a greater area than any acute triangle will show the statement is false:Consider the obtuse triangle with sides 25, 25, 40 cm; andthe acute triangles with sides 2, 2, 2 cm and 40, 40, 40 cmArea of (A) obtuse triangle = 40 x 12 ÷ 2 = 240 cm2Area of (B) acute 2, 2, 2 cm triangle = 2 x √3 ÷ 2 = √3 cm2 ~= 1.7 cm2Area of (C) acute 40, 40, 40 cm triangle = 40 x (20 x √3) ÷ 2 = 400 x √3 cm2 ~= 692.8 cm2So you can clearly see that area of acute triangle (C) is greater than that of obtuse triangle (B) which is greater than acute triangle (A).Thus the area of obtuse triangle (B) is not greater than that of any acute triangle.(Obtuse triangle A has angles approx 37o, 37o, 106o, whereas triangles B and C are equilateral acute triangles with angles 60o, 60o, 60o.)
