What reading level is First Steps in Geometry book?
To quickly assess the difficulty of the text, read a short excerpt:
Area of triangle BBC =^BC X BF=^BC X BE.
Adding, we have area of trapezoid = 1 (AB + BC) X BE, a result which we may state as follows : Area of a trapezoid = l (sum of bases) X altitude. EXERCISES Find the area of a trapezoid, having given : 1. Bases 10 in. And 8 in. , altitude 6 in.
2. Bases 20 cm and 30 cm, altitude 5 cm.
3. Bases 37 ft. And 25 ft. , altitude 19 ft.
4. Find in square miles the area of the trapezoid ABCD (Fig. 163), iiAB = ^ mile, CD = ^ mile, DE = \ mile.
5. The four lateral ...faces of the pedestal of a statue are equal trape- zoids (Fig. 164). The bases of each trapezoid are 20 ft. And 15 ft. In length. The altitude of each trajje- zoid is equal to 8 ft. What is the entire lateral surface?
6. A playground has the shape of an isosceles trapezoid. The bases are 600 ft. And 200 ft. In length, and the larger base makes angles of 60° p^^ ^^ with the legs. Construct a plan of the playground, taking 1 cm to represent 50 ft. , and find the area of the playground in square feet.
