The garden is a rectangle, 800.25 square meters in area. Calculate the garden's perimeter if its length is 48.5 m. - A rectangular patio
A rectangular patio measures 20 ft by 30 ft. By adding x feet to the width and x feet to the length, the area is doubled. Find the new dimensions of the patio. - Diamond and diagonals
A diamond has diagonals f = 8 cm and g = 6 cm long. How long is this diamond perimeter? (Calculate it!) - Rectangular garden
Divide a square garden with a perimeter of 124 m into two rectangular gardens, with the fence of one garden 10 m longer than the fence of the other. What dimensions will these rectangular gardens be? - Interior angles
You know the size of the two interior angles of the triangle alpha = 40° and beta = 60°. Calculate the size of the third interior angle. - Football Field Width
The football field has an area of 75.75a. What is the width if its length is 101 m? - Two diagonals
The diagonals of rhombus EFGH are in the ratio 1:2. What is the perimeter of the rhombus if the longer diagonal is 8 cm? - Rectangle
