Working out area in shapes SQUARES DT MATHS

Working out area in shapes - SQUARES. DT MATHS A square has four sides, with each being equal in length. Each of the four internal angles are right angles, 90 degrees. To work this our you multiply the length by the width. w l The formula is always in mm 2 AREA = X² AREA = 80 mm x 80 mm Area length x width AREA = 6400 mm² 80 mm Calculate the areas of the squares below. Ensure to demonstrate your working out and write your response in the box provided. 100 mm 70 mm 210 mm 55 mm 30 mm © HDU

Working out area in shapes - RECTANGLES. A rectangle has four sides, with the opposite sides being the same length and parallel. Each of the four internal angles are right angles, 90 degrees. AREA = X multiplied by Y AREA =LENGTH x HEIGHT The formula is always in mm 2 X AREA = 100 mm x 50 mm Y FORMULA AREA = 5000 mm² 100 mm 85 mm 50 mm Calculate the areas of the squares below.

Working out area in shapes - TRIANGLE. MATHS DT A triangle can be regarded as a polygon with three sides. The area of a triangle is calculated by multiplying half the value of the base by its height. h AREA = 1/2 X BASE X HEIGHT 50 mm b AREA = 40 x 50 2 2000 AREA = 2 AREA = 1000 mm² AREA = ½ X Base X Height 40 mm 75 mm 45 mm 30 mm 60 mm 35 mm 50 mm 80 mm 40 mm © HDU
