面积周长练习题及答案一、选择题1. 一个正方形的边长是4厘米，它的周长是多少厘米？A. 8厘米B. 12厘米C. 16厘米D. 20厘米答案：C2. 一个长方形的长是10厘米，宽是5厘米，它的面积是多少平方厘米？A. 30平方厘米B. 40平方厘米C. 50平方厘米D. 60平方厘米答案：C3. 一个圆的半径是3厘米，它的周长是多少厘米？（圆周率取3.14）A. 18.84厘米B. 21.98厘米C. 28.26厘米D. 36.5厘米答案：A二、填空题4. 如果一个三角形的底边长是6厘米，高是4厘米，那么它的面积是________平方厘米。

答案：12平方厘米5. 一个平行四边形的底边长是8厘米，高是3厘米，它的面积是________平方厘米。

答案：24平方厘米6. 如果一个圆的直径是14厘米，那么它的面积是多少平方厘米？（圆周率取3.14）答案：153.86平方厘米三、计算题7. 一个梯形的上底是5厘米，下底是10厘米，高是4厘米，求它的面积。

解：根据梯形面积公式 S = (a + b) * h / 2其中 a = 5厘米，b = 10厘米，h = 4厘米S = (5 + 10) * 4 / 2S = 15 * 4 / 2S = 60 / 2S = 30平方厘米8. 一个正六边形的边长是3厘米，求它的周长和面积。

解：正六边形的周长是边长的6倍，所以周长 P = 6 * 3 = 18厘米面积 A = 6 * (边长^2) / (4 * √3) = 6 * (3^2) / (4 * √3)A = 54 / (4 * √3)A = 27 / √3A ≈ 48.98平方厘米四、应用题9. 一个花坛是一个圆形，半径是5米。

如果沿着花坛的边缘铺设一圈小石子，小石子的总长度是多少？花坛的面积是多少？解：根据圆的周长公式C = 2πr，其中 r = 5米C = 2 * 3.14 * 5 = 31.4米根据圆的面积公式A = πr^2A = 3.14 * 5^2 = 3.14 * 25 = 78.5平方米10. 一块长方形的菜地，长是25米，宽是15米。

五年级最难数学题一、小数乘法部分。

1. 一个长方形的长是3.5米，宽是2.4米，这个长方形的面积是多少平方米？- 解析：根据长方形面积公式S = a× b（S表示面积，a表示长，b表示宽），这里a = 3.5米，b=2.4米，所以S=3.5×2.4 = 8.4平方米。

2. 0.25乘4.8的积是多少？- 解析：0.25×4.8 = 0.25×(4 + 0.8)=0.25×4+0.25×0.8 = 1+0.2 = 1.2。

3. 每千克苹果3.8元，买2.5千克苹果需要多少钱？- 解析：根据总价=单价×数量，单价是3.8元/千克，数量是2.5千克，所以总价为3.8×2.5 = 9.5元。

二、小数除法部分。

4. 3.6除以0.9的商是多少？- 解析：根据除法的运算，3.6÷0.9 = 36÷9 = 4。

5. 把5.6平均分成0.7份，每份是多少？- 解析：5.6÷0.7 = 56÷7 = 8。

6. 一种铁丝0.5米重0.4千克，这种铁丝每米重多少千克？- 解析：求每米的重量，用重量除以长度，0.4÷0.5 = 0.8千克。

三、简易方程部分。

7. 解方程3x+5 = 17。

- 解析：首先方程两边同时减去5，得到3x+5 - 5=17 - 5，即3x = 12，然后方程两边同时除以3，3x÷3 = 12÷3，解得x = 4。

8. 一个数的4倍比这个数多12，这个数是多少？（设这个数为x）- 解析：根据题意可列方程4x-x = 12，即3x = 12，解得x = 4。

9. 小明有x颗糖，小红的糖比小明的2倍少3颗，小红有15颗糖，求x。

- 解析：根据题意可列方程2x - 3 = 15，方程两边同时加3得到2x-3 + 3 =15+3，即2x = 18，然后两边同时除以2，2x÷2 = 18÷2，解得x = 9。
