What is the area of the polygon below?
84 sq. units
What is the area of a triangle if all the sides are 6 units long?
9*sqrt(3)= 15.588 sq units (to 3 dp)
If the two legs of a right triangle are 7 and 16 units long what is the triangle's area?
56 sq. units A = 1/2 Base x Height A = 1/2 (7 x 16)
Can you find the base and height for a triangle if you know that the area is 22 square units?
Without further information it is impossible to say exactly what the base and height are:area_triangle = 1/2 x base x height→ height = 2 x area_triangle ÷ base= 2 x 22 sq units ÷ base= 44 sq units ÷ baseSo for any base > 0 units a corresponding height will be found, eg:base = 1 unit → height= 44 sq units ÷ 1 unit = 44 unitsbase = 2 units → height= 44 sq units ÷ 2 units = 22 unitsbase = 44 units → height= 44 sq units ÷ 44 units = 1 unitbase = 88 units → height= 44 sq units ÷ 88 units =1/2 unitetcAll those triangles above have an area of 22 sq units.
What is the area of a perimeter of 2.4?
Any positive value upto 0.36 square units. A 0.6 x 0.6 square will have the maximum area of 0.36 sq units; a 0.5 x 0.7 rectangle will have an area of 0.35 sq units, and the area will be reduced as you reduce one of the measures and increase the other so that their sum remains 1.2 units so that the perimeter is 2.4 units. 0.1x1.1 will be 0.11 sq units 0.01x1.19 will be 0.0119 sq units 0.001x1.199 will be 0.001199 sq units 0.0001x1.1999 will be 0.00011999 sq units, etc.
